1 Claim.

This invention relates to adjustable spring cushion constructions; and particularly relates to adjustable cushion constructions in coiiins.

,One of the primary objects of the present invention is to provide a spring cussion construction which is adjustable, so that the cushion may be atfiusted to various degrees of inclination along its length.

Another object of the invention is to provide spring cushion constructions formed of a plu rality of hinged sections in which the sections may be adjusted to various degrees of inclination relative to a supporting surface and relative to each other. 7

Another object of the invention is to provide spring cushion constructions which are adapted to be placed in a box, particularly such as a comn, and which are adapted to be adjustably positioned within the box, or coflin, to various degress of inclination.

Another object of the invention is to provide improved and simplified, adjustable spring cushion constructions in which the spring cushions may be readily and easily adjusted to various degrees of inclination within a box structure while the spring cushion is loaded.

Other objects of the invention will become apparent from the following specification, the drawings relating thereto, and from the claim hereinafter set forth.

Referring to the drawings, and referring par ,cation is the licensee.

ticularly to Figs. 1 to 3, a box member l0, such as a coflin, is illustrated having side walls, end walls, and a bottom wall I2. Such box structures are generally made of an impressionable material, such as wood, so that the bottom member 12 is made of wood or some other impressionable material. The side walls and end walls may be lined with a cloth trim material II in the usual way.

According to the present invention, a spring cushion construction, generally indicated at ii, is adjustably mounted on the bottom member l2 within the box structure III. The cushion construction I6 includes a plurality of longitudinally extending, rectangular frame sections I8 and 20, which are hingedly mounted relative to each other by a suitable hinge structure 22. The frame section l8 forms the head portion and is preferably deeper at one end than the other so as to simulate a raised pillow construction for the head. The hinge structure 22 may be of any suitable construction, and in the embodiment illustrated comprises leather straps which are fixed to the upper surfaces of the adjacent sections so that a slight space is left therebetween to permit relative pivotal movement between the frame members l8 and 20.

A plurality of transversely extending, longitudinally spaced spring elements 24 are fixed to the opposite sides of the spring sections it and 20, respectively, to provide a resilient load supportin surface. The spring elements 24 are preferably of the zig-zag type disclosed in the Kaden Patent No. 2,002,399, issued May 21, 1935, under which the assignee of the present appli- The spring elements 24 are bowed upwardly and are secured at their ends to the sides of the frame sections by means of clips 28, or the like.

The spring load supporting surface formed by the spring elements 24 is covered by a fabric layer 28 having padding material 30 superimposed thereon with an outer layer 32 of suitable trim material. The ends of the fabric material 28 and 32 may be tacked under the edges of the side members of the frame sections l8 and II in the usual way.

According to the present invention in order to adjustably mount thesectlons i8 and 20 of the spring cushion construction relative to the supporting member I2 and relative to each other so.

that the spring supporting surface may assume various degrees of inclination therealong, adjustable mounting means are provided. These adjustable mounting means include elongated pivot members 40 having pointed lower ends 42 which are oppositely disposed and pivotally fixed to the sides of the frame sections I8 and 20, respectively, by means of screws 44, or the like. The left hand end of the construction I6, as viewed in Fig. 1, may be considered as the head end of the structure, and the members 40 are preferably provided adjacent the, head end of section I8 at each side of this section. The members 40 which are pivotally mounted to the section are preferably located near the juncture of the section 28 with section I8, so that the head end and the intermediate portion of the structure I6 may be adjusted to various degrees of inclination relative to the foot end, which may rest directly on the bottom member I2. Cross-members 48 extend between the opposite members 40 so as to brace the adjustable means and to insure uniform movement of the opposite supporting members 40 so that the frame structure is not transversely tilted as it is raised and lowered.

To pivot the members 40 on the section 28, a cord member 50 is provided which is attached to the cross-brace 48 at each side of the brace adjacent the members 40. The cord 50 is adapted to extend upwardly through openings in the fabric 28, the padding 30 and the trim material 32 so that a portion of the cord lies on the top surface of the trim material 32 where it is readily accessible. A similar cord 52 is provided for attachment to the cross-member 48 on the sec tion I8 which is also adapted to extend through similar openings in the padding and trim material; and such openings are preferably provided closely adjacent the head end corner of the section I8, preferably close to the transverse center, so that the cord is readily accessible, even while a body is reclining on the structure.

The pointed supporting members 40 are hinged at their upper ends so that as the sections I8 or 20 are raised by hand the weight of the members 40 causes the pointed ends at all times to remain in contact with the upper surface of the bottom member I2. When the frame sections are released, the weight of the spring construction and the weight of a body reclining thereon cause the pointed ends 42 to ibight into the impressionable surface of the member I2 so that the sections I8 and 2'0 are held in their desired vertical positions to give the desired degree of inclination. The angular position of the members 40 for both sections I8 and 22, which angular position controls the extent of elevation of the sections, may be readily controlled by pivoting the members 48 by means of the cords 50 or 52. Hand straps 56 may be provided at spaced intervals along the length of the cushion construction I6 at the sides and ends thereof, which hand straps provide a convenient means for grasping and raising the frame sections I8 and 20.

In Figs. 4 to 6 a modified form of the present invention is illustrated in which the two sections I8 and 20 are not hingedly connected together, as in the embodiment described above, but are mounted independently of each other within the comn III.

The section 20, adjacent the foot of the coflin, is mounted a fixed distance from the floor I2 on longitudinally extending supporting members 60. Such longitudinally extending members 60 may be suitably fixed to the sides of the coflln -at predetermined distances from the bottom thereof; and the frame of the coflin 20 may rest upon the upper surfaces of the supporting members so that the section 60 may be removed from the coflin.

The section I8, forming the head of the cushion construction, is pivotally mounted to the coflln by means of pivot pins 62 located adjacent the section 20. The pivot pins 62 are pivotally received within suitable supporting means which may be in the form of rings attached to the inner sides of the side walls of the coffin. The pins 62 extend within such rings so that the forward end of section I8 is pivoted relative to the bottom with the forward end at a predetermined distance from the bottom of the coflin and preferably at the same height as the height of section 20.

In order to adjustably mount the section I8 so that it may be adjusted to various degrees of inclination, a link chain 64 is fixed to the head end of section I8 at substantially the transverse center thereof, by means of a suitable connection 66. The link chain 64 is adapted to extend upwardly through an opening 68 in a bracket member 10. The bracket member I0 may be suitably fixed to the inside wall of the head end of the coflln. A slot 12 communicates with the opening I8 so that the chain 64 may be moved through the opening 68 and may be fixed in position by having one of the links of the chain received within the slot I2 so that the adjacent link, which is at right angles to the link within the slot, bears against the upper surface of the bracket III over the slot I2 so that the head end of section I8 is properly supported. By suitably adjusting the length of chain between the bracket 10 and the member 66, the section I8 may be adjusted to the desired degree of inclination.

In Figs. '7 and 8 a modified form of the structure illustrated in Figs. 4 i to 6 is shown, in which the section 2'0 may be vertically adjusted relative to the floor I2. Upstanding supporting members 80 in the form of metal stampings and preferably generally U-shaped in cross section, are suitably fixed to the side walls of the coffin adjacent each corner of the section 20. The members 80 each have an inwardly facing major portion 82 which is spaced from the inner walls of the coflin. Generally circular openings 84 are provided through the faces 82 at vertically spaced intervals. Elongated narrow slots 86 communicate with their respective openings 84 adjacent the lower ends thereof; and pin members 90 having heads 92 may be removably received within the slots 86. The heads 92 are slightly smaller in size than the openings 84 so that the heads 92 may be inserted through any one of the openings 84; and when so inserted the pin portion drops within the corresponding slot 86 and is fixedly supported therein. Blocks 94 are fixed to the under surface of the section 20 adjacent each corner thereof, and such blocks are adapted to rest upon their corresponding pins 90.

It is evident from the above that by positioning the pins 90 in the desired openings 84 that the section 20 may be mounted for vertical ad- .lustment relative to the floor of the coffin. The section 26 may also be mounted at any desired degree of inclination by positioning the pins at the front end of the section at a lower level than the pins at the head end. It is also pointed out that the pivot pins 62 may be similarly mounted for vertical adjustment if desired.

Formal changes may be made in the specific embodiment of the invention described without departing from the spirit or substance 01' the invention, the scope or which is commensurate with the appended claim.

What is claimed is:

The combination of an elongated box member having side and end wall members, and a bottom member, an elongated cushion structure which is longitudinally divided into a plurality of frame members hingedly mounted relative to each other and extending the full length of the box member, transversely extending sinuous spring elements at spaced intervals longitudinal- 1y of said section providing the load supporting surface, means for mounting one of said sections at an inclination to said bottom member 1 with the end edge of said section resting on said bottom member, means pivotally mounting another 01' said sections relative to said bottom member and to said one of said sections, whereby said cushion structure may be mounted at difierent degrees of inclination throughout its HENRY HOPKES.
